The Provista/Radient merger you are quoting was cancelled several years ago. Today, Provista is not involved, in ANY way, with Radient.
But by all means, prove your case. Please tell us the patent number for even ONE Provista patent that involves Radient, DR-70, onko-sure, MacLellan, or CIT in ANY way.
The USPTO system is easy to search. I've done a lot of patent searches. I only see one existing patent for DR-70, and it expires in six weeks. I only see ONE patent pending for DR-70, and it was rejected, then resubmitted in Feb 2013 as an RCE, and currently sits in the RCE backlog queue. Research that I have posted several times shows that an RCE submitted in 2013 will not be reviewed for at least three years after submission. That's Feb 2016.
